Gas quenching furnaces are widely used in various fields such as aerospace, automotive manufacturing, precision machinery, mold manufacturing, energy and power, as well as scientific research and education. Their core advantage lies in the ability to achieve efficient, clean, and precise heat treatment, meeting the stringent requirements of high-end manufacturing for material performance. The specific application areas are as follows:

1. Aerospace field

Key component handling:

Gas quenching furnaces are used to process key components such as aircraft engine blades, turbine disks, and spacecraft structural parts. These components need to withstand enormous stress and temperature changes in extreme environments, and gas quenching can significantly improve their strength and fatigue resistance.

Advantages: Vacuum environment avoids oxidation, high-pressure gas cooling reduces deformation, and ensures component accuracy.

Lightweight material heat treatment:

Titanium alloys are widely used in aerospace, and gas quenching can control the heat treatment of their beta phase zone, optimize the alpha phase morphology, and improve fatigue performance.

Case: After gas quenching, the fatigue life of titanium alloy aviation fasteners is extended.

2. Automotive manufacturing field

Transmission and transmission components:

High precision heat treatment is required for automotive transmission gears, synchronizer bushings, and main reduction sun gear axles. Gas quenching can control distortion and improve dimensional stability.

Case: After gas quenching, a certain car company reduced gear tooth distortion and increased the pass rate.

Advantages: Clean and pollution-free, eliminating cleaning processes and reducing production costs.

Engine components:

Engine components such as crankshafts and connecting rods require high strength and wear resistance, and gas quenching can achieve precise temperature control to avoid cracking.

Case: After gas quenching, the crankshaft of the engine has higher hardness and improved wear resistance.

3. Precision Machinery Field

Mold manufacturing:

Die casting molds, plastic molds, etc. require high hardness and thermal stability. Gas quenching can reduce thermal distortion and extend mold life.

Advantages: No oxidation on the surface, reduced polishing process, and lowered maintenance costs.

Measuring tools and cutting tools:

Cutting tools and measuring tools require high hardness and dimensional accuracy, and gas quenching can achieve uniform cooling to avoid deformation.

Case: High speed steel cutting tools have higher hardness and good thermal hardening after gas quenching.

4. Energy and Power Sector

Wind and nuclear power components:

Wind turbine gearboxes, nuclear power valves, etc. require high strength and corrosion resistance, and gas quenching can improve material properties.

Case: After gas quenching, the fatigue resistance of wind turbine gears is improved, making them suitable for harsh environments.

Power equipment:

Transformer cores, motor shafts, etc. require high magnetic conductivity and mechanical strength, and gas quenching can optimize the organizational structure.

Case: After gas quenching, the magnetic permeability and efficiency of the motor shaft are improved.

5. Research and Education Fields

Material research and development:

Universities and research institutions use gas quenching furnaces to develop new materials and study the effects of different processes on tissue properties.

Case: After gas quenching, the distribution of carbides in the new cobalt based alloy is more uniform, and the wear resistance is significantly improved.
